Pyronema, Car. Resupinate, effused; hymenium furnished with 
highly developed asci containing large elliptic sporidia, accompa- 
nied by paraphyses. Circumference byssoid. 
That given by Nees Von Esenbeck stands thus : 
Resupinate, effused. Asci of the hymenium of two kinds, each 
bearing sporidia ; the more slender with globose coloured sporidia, 
the wider with larger oval hyaline erumpent sporidia. Circumfer- 
ence byssoid. 
Besides Pyronema marianum, Thelephora sulphurea is also re- 
ferred to this genus, which will come next to Thelephora. 
The propriety of such reference is perhaps at present uncertain. 
I do not restore the original specific name of Bertero, though in- 
finitely preferable to that given by Dr Carus, which refers to the 
circumstance of the plant being pointed out to him by his daughter, 
as it would be only adding to the number of synonyms with which 
mycology is already overburdened.

stems of nettles with or without Fusarium tremelloides. Apethorpe, 
Northamptonshire, March, April, 1836. 
At first sight, this beautiful species so strongly resembles in habit 
Fusarium tremelloides, that it is very difficult to believe that it can 
be anything more than a more perfect form of the same plant, and 
in consequence it has probably been overlooked^ Cups, scarce a line 
in diameter, shallow, scattered or gregarious, originating beneath 
the cuticle, scattered or collected in patches, at first subglobose, but 
slightly attached below, gradually expanding and more adnate with 
a rather thick, even, or flexuous border, orbicular or elongated, some- 
times confluent bright orange. Asci clavate, slightly flexuous, accom- 
panied by slender linear paraphyses, which are sometimes longer 
than the asci. Substance firm, not tremelloid, as in the Fusarium, 
which it so much resembles. Its nearest ally appears to be Peziza.
